According to Dale S. Beach, Human resource planning is a process of determining and assuring that the organisation will have an adequate number of qualified persons, available at the proper times, performing jobs which meet the needs of the enterprise and which provide satisfaction for the individuals involved.
How much sleep do teens need? Based on current data, we think that most teens need on the order of 9-plus hours nightly to have optimal sleep. The NSF poll data indicate that most teens fall short of this goal, many by a considerable amount. Although we think that the need for sleep does not really change across adolescence, the amount of sleep young people get does decrease in older teens.
This is far short of the desired quota for healthy teens. Find out how a lack of sleep affects school here. Researchers at Stanford University found in a study that teenagers require more sleep, by 1 to 2 hours, than do their younger 9- and 10-year-old siblings, who only require about 8 hours of sleep. This contradicts parents since we tend to give later bed times and curfews to our children as they get older.
